What is Ethereum and how does it differ from traditional cryptocurrencies?

Ethereum is a decentralized, open-source blockchain system that features smart contract functionality.

It is not just a cryptocurrency, but a platform for decentralized applications (dApps), which are applications that run on a peer-to-peer network of computers, as opposed to a single computer.

Ethereum’s cryptocurrency, called Ether (ETH), is used to compensate participants who perform computations and verify the network.

Unlike Bitcoin, which was created as an alternative to traditional currencies, Ethereum was intended for complex smart contracts and decentralized applications.

While both Bitcoin and Ethereum are digital currencies traded via online exchanges and stored in various types of cryptocurrency wallets, they differ in their primary purposes and technical aspects.

For example, Ethereum’s transactions may contain executable code, while Bitcoin’s data affixed to transactions is only used to record transaction information.

Additionally, their consensus mechanisms are different: Bitcoin uses proof-of-work, while Ethereum uses proof-of-stake.

Ethereum’s key characteristics include its attempt to solve the blockchain trilemma with a move to Proof of Stake, sharding, and more.

It also operates as a marketplace for users to buy and sell goods and services.

In summary, Ethereum differs from traditional cryptocurrencies like Bitcoin in that it is not just a digital currency, but also a platform for decentralized applications and smart contracts.

Its cryptocurrency, Ether, is used to compensate participants who perform computations and verify the network.

The technical differences between Ethereum and traditional cryptocurrencies lie in their primary purposes, consensus mechanisms, and the nature of their transactions.

How does Ethereum use smart contracts to enable decentralized applications and digital agreements?

Ethereum uses smart contracts to enable decentralized applications (dApps) by leveraging the Ethereum blockchain’s smart contract functionality.

Smart contracts are self-executing contracts that run on the Ethereum network and facilitate, verify, and enforce specific functions when predefined conditions are met.

These smart contracts allow dApps to operate in a decentralized manner, without the need for a central authority, and they are immutable, meaning that once deployed on the Ethereum network, they cannot be changed.

dApps are designed to be open-source, transparent, and resistant to censorship, allowing users to interact directly with the application without intermediaries.

They have been developed for a variety of purposes, including gaming, finance, and social media.

Ethereum’s flexible platform provides the infrastructure needed for developers to focus their efforts on finding innovative uses for dApps in various industries, such as banking and finance, gaming, social media, and online shopping.

The use of smart contracts and the decentralized nature of dApps offer benefits such as user privacy, lack of censorship, and flexibility of development.

However, they also present challenges such as scalability, user interface development, and code modifications.

What are the different types of accounts that exist in the Ethereum network, and how do they function?

In the Ethereum network, there are two main types of accounts: Externally Owned Accounts (EOAs) and Contract Accounts (CAs).

Externally Owned Account (EOA)

An EOA is the most basic type of Ethereum account.

It is controlled by a private key and is used by individuals.

Some key points about EOAs are:- It is created whenever a wallet is created and is made with a private key that is required to access the account, check balances, send and receive transactions, and establish smart contracts.

– An EOA can initiate transactions and can only be used for ETH/token transfers.

– It is made up of a cryptographic pair of keys: public and private keys that control account activities.

Contract Account (CA)

A CA is a smart contract deployed to the network and controlled by code.

Some key points about CAs are:- It can only send transactions in response to receiving a transaction and can trigger code that can execute various actions, such as transferring tokens or creating a new contract.

– Creating a contract account has a cost because it uses network storage.

– It does not have private keys; instead, it is controlled by the logic of the smart contract code.

Both types of accounts have the ability to receive, hold, and send ETH and tokens, as well as interact with deployed smart contracts.

In summary, EOAs are controlled by private keys and are used by individuals, while CAs are smart contracts deployed to the network and are controlled by their associated code.
